Improvement in machines for making paper twine



A UNITED 'STATES Perfhilhee- JOHN B. WORTEDYKE, OF GOODWINVILLE, NEW JERSEY lMPROVEMENT l-N MACHINES FOR MAKlNG PAPER. TWINE, &o.

Specication forming partof Letters Patent No. 42,896, dated May 24, 1864.

To all whom itt/.may concern: Be it known that I, JOHN B. WOR'IENDYKE,

-of Goodwinville, in the county of Bergen and 2 is a transverse vertical section of the same.

Fig. 3 is a front view illustrating a modifica, tion of the machinery employed in carrying out my invention. Fig. 4 is a transverse vertical section corresponding with Fig. 3.

Similar letters of reference indicate corresponding parts in both figures.

. The object of this invention is to effect the manufacture of twine of good quality from machinery substantially like that employed in spinningcotton and other fibrous materials, consisting mainly of pressure-rollers arranged substantially like the drawing-rollers of spinning-frames, and athrostle or spindle, applied and operating substantially like those ot' such frames. The paper is cut into a strip of pr )per width to forni the twine, and of as greatlength as possible, and placed on a roll, whence it is taken by the aforesaid pressure-rollers.

In order to enable the strip to be well spun, it is moistened and afterward gathered up laterally into the form of roping, during its passage to or between the prcssurerollers, and it is in this moistening and lateral gathering up of the strip while it is on its way to the throstle or spindle that my invention consists.

A is the roll from which the strip of paper is supplied, arranged behind the back pair of pressure-rolls, B B', in bearings in which it is free to turn freely, to allow the strip to be drawn oii' as fast as required by means of the said pressure roliers.- These pressure-rollers may be of wood or oth-er material, and the necessary pressure of the top roller, B', may be obtained by any suitable system of loading.. The lower roller, B, (represented in Figs. l and 2,) has arranged below it a troughlor box,-C, containing water, in which its lower part rotates for the purpose of taking up a sufcient quantity for moisteningthe paper as it passes between the said roller andthe upper roller, B'. To enable the said rollerB to take up a larger quantity of water and apply the same to the paper in a better manner than if it had a perfectly even surface, itis groovcd circumferentially atshort intervals.

l Figs. 3 and 4 represent a perforated or iin'ely slit steam-pipe as a substitute for the trough G, the said pipe being arranged as close as practicable in front of the rollers B B', and in such a manner as to deliver the steam directly upon the under surface' of thc strip of paper, and thereby moisten it as it emerges from between the said rollers.

Between the back pressure-rollers, B B', and the front ones, D D', there is arranged a taper spout-like guide, E, of tin-plate or other metal or material, through which the strip of paper (represented in yellow color) has to pass on itsvway from one pair of rollers to the other.

'The entrance of this guide is of a width not less than the full width of the strip of paper of which the twine is to be made; butits outlet, which is brought as far as possible into the entrance between the rollers D D, is very A tuted for the spout-like guide E, and will have.

the saine eifeot. The pressure-rollers B B and D D' are or may be driven in the same manner as the back and lfront drawing-rollers of spinning-frames for spinning cottonv and other brous substances, except that the front pressure-rollers do not require to have any higher velocity, as no draft is intended to be produced. By the moistening of the paper on its way to the throstle or spindle by which it is spun intotwine, it is softened and so enabled to be easily gathered up laterally into the form of roping, and to be easily spun and retain its twist after being spun. By gathering up the strip laterally into the form of rop- .ing, it is enabled to be much better twisted.

The moistening of the paper sufficiently with perfect uniformity can only be effected while it is on its Way from the roll A or its equivalent to the tllrostle or spindle, for it' moistened while or before being' placed on the roll it is not possible to deliver the whole length oi' a piece at a uniform dampness. The twine thus produced is very uniform and smooth, and may be used as strands for cord. l

What I claim as my improvement in the manufacture of palper twine, and desire to secure by Letters Patent, is-

l. The moistening of the strip of paper of which the twine is to be formed While on its. Way to or between the rollers by which itis delivered to the spindle or throstle by whieh the twisting 1s performed, substantially kasA herein described.

2. The employment, in combination with mea-ns of moistening the strip of paper on its Way to the spindle or throstle, of a guide, E,4
